The following glossary is adapted from the glossary provided by Planned Parenthood at https://www.plannedparenthood.org/learn/glossary.
Vagina: The stretchable passage that connects a woman’s outer sex organs, the vulva, with the cervix and uterus. The vagina has three functions: to allow menstrual flow to leave the body, to allow sexual penetration to occur and to allow a fetus to pass through during vaginal delivery.
Vaginal atrophy: Thinning and irritation of the folds of the walls of the vagina caused by the normal reduction in the secretion of estrogen during perimenopause and after menopause.
Vaginal contraceptive film / vcf: A thin, two-inch square sheet of chemicals that is inserted deep into the vagina, and melts into a thick liquid that blocks the entrance to the uterus with a spermicide. It immobilizes sperm and prevents it from joining with an egg. An over-the-counter, reversible barrier method of birth control. Most effective when used with a condom.
Vaginal intercourse: Sex in which a penis enters a vagina.
Vaginal lubrication: During sexual arousal, the secretion of a slippery fluid from the blood vessels that “perspires” through the rugae of the walls of the vagina into the vaginal canal to facilitate penetration.
Vaginitis: An irritation of the vagina or vulva.
Values: Ideas about what is right, worthwhile, or moral.
Varicocele: An enlargement of one or more of the veins that carry blood away from the testis. It can reduce blood flow and increase the temperature of the testicle, thereby causing infertility. Similar to varicose veins that occur in the leg.
Vas deferens: A long, narrow tube that carries sperm from each epididymis to the seminal vesicles during ejaculation. The plural of vas deferens is vasa deferentia.
Vasectomy: Surgical blocking of the vasa deferentia in men that is intended to provide permanent birth control.
Vasocongestion: An increase in the amount of blood in certain body tissues (breasts, clitoris, inner labia, nipples, penis) that is caused by sexual arousal. Also causes sex flushes and lubrication of the vagina.
VD: Venereal disease (outdated).
Viability: The ability of a fetus to survive outside a woman’s body.
Virginity: The status of never having had sexual intercourse.
Vulva: A woman’s external sex organs, including the clitoris, labia (majora and minora), opening to the vagina (introitus),opening to the urethra, and two Bartholin’s glands.
